RobotCoding Software


Cheese Stick User’s Manual 


  • Connect the USB Dongle to the USB port
  • Turn the Cheese Stick ‘ON’
  • Pair the Cheese Stick with USB Dongle by placing them within 15 cm.
  • Launch RobotCoding software and check the connection status for Cheese Stick
  • Select the options in RobotCoding software and launch Scratch (offline/ online)
  • Use Scratch Software


1. Connect the USB Dongle to the USB port on the PC. If you see the blue light blinking, everything is working correctly.


2. Turn the Cheese Stick Switch ON.



3. You must pair your Cheese Stick and USB Dongle when you use Cheese Stick for the first time. The cheese Stick and USB Dongle are not connected. We need to connect them by placing the two near each other. This process is called “pairing.” Place Cheese Stick and USB Dongle within 15 cm distance once. The paired Cheese Stick can connect to the USB Dongle within 15 cm distance. You can pair the two with a different PC because the USB Dongle remembers the Cheese Stick it was lats paired to.


-When not being paired: the Bluetooth connection indicator LED for Cheese Stick and USB Dongle will blink slowly.

-Place the Cheese Stick near USB Dongle.

– Cheese Stick will make a beep and the Bluetooth connection indicator LED will turn on in blue.

-The LED will start to blink rapidly if RobotCoding software is running.



4. Start RobotCoding Software

– Hearing a beep from Cheese Stick and the blue light of LED is blinking rapidly means a pairing has formed and is running. You are able to see the description for Cheese Stick on the right side of RobotCoding page. Blue button background means normal connection.

*You can find the RobotCoding software start file in C:\RobotCoding (Windows) or Application (MacOS)


  • If you don’t see the description for Cheese Stick on the RobotCoding main page and the blue LED Bluetooth light is continuously on, it means the Cheese Stick and the USB Dongle formed a pair but the RobotCoding program is unable to recognize the USB Dongle.
  • First, restart the RobotCoding software. If the problem continues, reinstall the USB Dongle Driver or check to see if you have a driver conflict.


  • If you see the blue LED light is blinking slowly and no description of Cheese Stick on the RobotCoding main page, no pairing has formed between Cheese Stick and the USB Dongle. Since the device cannot connect to the program, pair them first. Be sure to check if the device is fully charged.


Things to watch out when forming pairing between Cheese Stick and USB Dongle as well as using it via RobotCoding


– A Cheese Stick and USB Dongle pairs only when they are within 15 cm of each other. You can pair many Cheese Sticks and USB Dongles at once.

-Once the pairing has formed, Cheese Stick and the USB Dongle don’t need to be paired again. You can still connect them by simply turning them on as long as they are within 15 m of each other.

-You can use many Cheese Stick at once. The USB Dongle will store the Cheese Stick information it last paired and will connect with that Cheese Stick.

-The USB Dongle will not pair with a new device if it is already paired. Turn OFF the device and pair with the new device if you want to form a new pair.


5. Select the Scratch version you want to use. RobotCoding supports Scratch 2.0/3.0/X.


6. Select Single Robot or Multiple Robot option. Click “Back” to return to previous page.


7. Select from Level 1, Level 2, Level 3. Each level provides different types of coding blocks for the connected devices. To use all the blocks, select Level 3.



8. Scratch software will start.

Don’t close the RobotCoding software while you are using Scratch through RobotCoding. RobotCoding software accepts signals from Scratch and transfers it to Cheese Stick, and transfers the sensor values of hardware Scratch to Scratch.



9. You can find all Cheese Stick-related blocks on “more blocks” (Scratch 2.0) and Cheese Stick tab (Scratch 3.0).

– There is a green circle on top right corner of Block Categories. Green Checkmark indicates the device is connected to PC. Orange exclamation mark indicates connection problem

-You can get more detailed information when you click on the circle.
